Q1: What is the primary chemical class of Hansa Yellow G 02?
A: Hansa Yellow G 02 is an organic pigment belonging to the monoazo class, specifically derived from acetoacetarylide chemistry, offering balanced hue, transparency, and tinting strength suitable for demanding industrial applications.
Q2: Is this pigment suitable for use in food-contact plastics?
A: Hansa Yellow G 02 is not approved for direct food-contact applications under major global regulatory frameworks. It is intended for general-purpose industrial plastics, coatings, and inks where regulatory compliance for food contact is not required.
Q3: How does Hansa Yellow G 02 perform in terms of heat stability?
A: This pigment demonstrates good thermal stability for standard processing conditions in polyolefins and PVC, typically up to approximately 180–200 °C. Performance may vary depending on residence time, shear, and resin matrix — stabilization additives and processing optimization are recommended for high-temperature applications.
Q4: What is the typical dosage range when using this pigment in plastic masterbatches?
A: Dosage depends on the desired shade intensity and base polymer, but it is generally used at low concentrations — typically ranging from 0.1% to 2% by weight in final plastic articles. Optimal loading should be determined through lab-scale trials to balance color performance, dispersion quality, and cost efficiency.
Q5: Can Hansa Yellow G 02 be used in water-based systems?
A: Yes — with appropriate surface treatment or formulation assistance, Hansa Yellow G 02 can be dispersed in water-based inks and coatings. However, its native hydrophobic character requires careful selection of dispersants and stabilization strategies to achieve consistent rheology and long-term colloidal stability.
